Hierarchical Structure

TYPO3 is a content management system (CMS) that helps you organize and manage your website. Its hierarchical structure is like a family tree for the content of your website.

1. Start page: The start page is at the top. It is the starting point of your website.
2. Subpages: Below the home page, you can have several subpages. These are like branches on a tree, each representing different sections of your website.
3. Content elements: Within each subpage, you can add content elements such as text, images or videos. These are the leaves on the branches that show the actual content that visitors will see.

This structure helps keep your website organized, making it easier to manage and update.
